$PECIPICATION forming part of Letters Patent No. 370,431, datedSeptember 27, 1887.

Application filed May 23, 1887.

.To all whom it may concern.-

l 3e it known that I, J. BENNETT WALLACE, a citizen of the UnitedStates, residing at Ohinois, have invented a new and useful Improvementin Vapor Cooking-Stoves, of which the following is a specification. I

In a prior application filed by me I have shown a vapor cooking-stoveembodying an oven located below the top plate and a separate broiling orroasting chamber locatedbclow the oven, both oven and broilingchamberbeing heated by a burner or burners located between'them, and both beingcapable of use at the same time. My present invent-ion is a modificationof that stove, and in it I dispense with the separate broilingchamber byplacing in the top of the oven a burner adapted to reflect heatdownwardly upon food placed therein, thereby adapting the oven to useeither as a broiling-chamber or baking-oven, as occasion requires. Thisadded burner, as well as the burner heating the oven from below, arenongenerating burners, andare both connected to the genbranched pipe, soas to be regulated by the same needle-valve, but the pipe-connection itsbranch with the main portion, whereby the vapor may be directed to thatone of the burners which it is desired to use and shut off from theother one.

The invention consists in the combination, with the oven of avapor-stove, of separate non-generating burners located in its top andbottom, a branched pipe-connection between said burners and thegenerator of the stove, a single needlevalve regulating the supply ofvapor to said burners, and a valve or valves located in theconnecting-pipe for directing the flow of the vapor to that one of theburners which it is desired to use.

In the accompanying drawings, which form a part of this specification,and in which similar letters of reference indicate like parts, Figure 1is an elevation of "a stove embodying my present invention. Fig. 2 showsthe Serial No. 239.039. )S'o model.)

stove, the view being partly in sectionand h plate, 13 the reservoir, 0the generatinga may burner, and D the oven, of the stove. represent anon-generating burner used in the top plate, and m a needle-valvecontrolling the same.

The oven is furnished with a burner, c, at the bottom, as usual, for usewhen baking is to be done, and also with an interior burner, d, at thetop, for use in roasting or broiling. This latter burner is inverted andsurrounded by the deflecting-plate 1), whereby the flame is caused tospread out in a thin horizontal sheet, the products of combustionescaping in the direction indicated by the arrows in Fig. 2. Both theseburners are non-generating,

and are fed from the generator 0, as hereinafter stated.

G is a needle-valve stern regulating the supply of vapor to both theoven-burners. By it the vapor is admitted into the mouth of a pipe, E,which is provided with a branch, 6, leading to the lower oven-burner,while the main portion is extended over the oven to the upper burner,(Z, as plainly indicated in Fig. 2. At the junction of the branch andmain pipe is located a rotary valve, F, operative by the handle f, andacting to direct the current of vapor to the upper or lower burner, asdesired. As shown in Fig.2, this valve is in position to shut off accessby the vapor to the lower burner and admit it to the upper one. Any formof valve adapted to control the passages to both burners will an swer inthis place, and I have illustrated a three-way valve of ordinaryconstruction, and hence I do not wish to be limited to, the one shown,and, indeed, separate valves might be placed in the branch and extendedpipes with the same result, so far as controlling the vapor isconcerned. By changing the valve or valves employed to direct thecurrent the oven is instantly converted into either an oven proper or abroiling or roasting chamber.
